... transmissivity of multicomponent GCLs when the coating or attached film is damaged over an area large enough to make edge effects negligible. For all multicomponent GCLs characterized, the coating or attached film was less than 0.7 mm thick. Steady-state results indicated flow rates ranging from 4.61 × 10...

...S. Bourgès-Gastaud; E. Blond; N. Touze-Foltz ABSTRACT: Hydraulic transmissivity is the most important design parameter of geocomposites used for in-plane drainage applications. This paper presents an in-depth investigation of the hydraulic behaviour of drain-tube planar geocomposites (DTPGs...

... geocomposites in transmissivity tests. The conventional geocomposites had a geonet or a geospacer as drainage core, whereas the alternative geocomposites had drainage cores made of bottle caps or tyre strips. The results showed similar performance for conventional and alternative geocomposites. It was also...

...H.M. Abuel-Naga; A. Bouazza; E. Lalot ABSTRACT: This paper presents a new approach to the utilisation of a flexible-wall permeameter to measure the hydraulic transmissivity of a geotextile. The proposed method is simple, and requires neither additional equipment nor a special test procedure...

... designed for this purpose. The tests performed were aimed at verifying the influence of the structural and material properties of the GCL on the transmissivity along the GM–GCL interface and flow rates through composite liners. Four types of GCLs with two different bonding processes (stitch-bonded...

... importance if the leakage rate of a GCL/GM composite barrier with a defect in the geomembrane needs to be assessed effectively. The present paper reports on interface gas transmissivity measured in a specially made cell. It was found that the gas transmissivity ranged between 2 × 10⁻⁷...

...R.J. Fannin; H.W. Choy Transmissivity tests were performed on a geonet confined between a pair of geomembranes under five increments of compressive stress ranging from 25 to 400 kPa. Each successive increment of stress was applied for 24 hours. In total, four geonets and seven geomembranes were...
